**Finding Critical Values and Rejection Regions for a t-Test**

To perform a statistical t-test, you need to determine the critical value(s) and rejection region(s). Here is how to do it for the given parameters:

1. **Test Type**: Left-tailed test
2. **Significance Level (\(\alpha\))**: 0.01
3. **Sample Size (\(n\))**: 28

Steps:

- Click the icon to access the t-distribution table.
  
- Locate the critical value for a left-tailed test with 27 degrees of freedom (\(n-1\), since \(n = 28\)) and a significance level of 0.01.

- Enter the critical value(s) in the provided box (Round to the nearest thousandth as needed). Use a comma to separate answers if there are multiple critical values.

**Additional Instructions**: Ensure that you round the values appropriately and consult the t-distribution table if necessary to identify the exact critical values.
